Abstract

BACKGROUND: Perfluoroalkyl substances (PFAS) have drawn much attention due to bioaccumulation potential and their current omnipresence in human blood. We assessed whether plasma PFAS, suspected to induce endocrine-disrupting effects, were prospectively associated with clinical type 2 diabetes (T2D) risk. METHODS: We established a nested case-control study within the Swedish prospective population-based Västerbotten Intervention Programme cohort. Several PFAS were measured in plasma from a subset of 124 case-control pairs at baseline (during 1990-2003) and at 10-year follow-up. T2D cases were matched (1:1) according to gender, age and sample date with participants without T2D (controls). Conditional logistic regressions were used to prospectively assess risk of T2D by baseline PFAS plasma concentrations. Associations between long-term PFAS plasma levels (mean of baseline and follow-up) and insulin resistance (HOMA2-IR) and beta-cell function (HOMA2-B%) at follow-up were prospectively explored among 178 and 181 controls, respectively, by multivariable linear regressions. RESULTS: After adjusting for gender, age, sample year, diet and body mass index, the odds ratio of T2D for the sum of PFAS (Σ z-score PFAS) was 0.52 (95% confidence interval, CI: 0.20, 1.36), comparing third with first tertile; and 0.92 (95% CI: 0.84, 1.00) per one standard deviation increment of sum of log-transformed PFAS. Among the controls, the adjusted β of HOMA2-IR and HOMA-B% for the sum of PFAS were -0.26 (95% CI: -0.52, -0.01) and -9.61 (95% CI: -22.60, 3.39) respectively comparing third with first tertile. CONCLUSIONS: This prospective nested case-control study yielded overall inverse associations between individual PFAS and risk of T2D, although mostly non-significant. Among participants without T2D, long-term PFAS exposure was prospectively associated with lower insulin resistance.

  • Several prospective cohort studies have reported that exposure to PFASs may increase the risk of T2D, as well as the potential positive association with IR.

    “Several prospective cohort studies have reported that exposure to PFASs may increase the risk of T2D, as well as the potential positive association with IR (Donat-Vargas et al., 2019; Margolis and Sant, 2021; Roth and Petriello, 2022; Sun et al., 2018).”

    The Results and Conclusion report the opposite for this prospective study: PFAS exposure was generally associated with lower T2D risk and lower insulin resistance, not increases in either. The Discussion acknowledges one earlier prospective study with positive T2D associations, but says prospective findings were conflicting and that prospective associations with insulin resistance in another study were null. (LLM, conf=0.88)

    Checked by a reasoning model — may be wrong.

  • There is limited study linking PFAS exposure to Type 2 diabetes, with low risk and uncertain long-term impact in adults.

    From Industrial Applications, Environmental Fate, Human Exposure, and Health Effects of PFAS (2025) · cites this paper as [231]

    The Introduction describes the epidemiological evidence linking PFAS exposure to type 2 diabetes as limited and inconsistent. The Conclusion reports no adverse effect in this study and calls for further work to evaluate potential metabolic effects, supporting uncertainty about longer-term impact. It does not establish a generally low diabetes risk for adults; the Introduction also notes studies reporting positive associations. (LLM, conf=0.85)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
